No, they're not.
It is plainly ridiculous to say that photographic style preferences, regarding sharpening and noise, are not subjective. It's not even worth debating this. I don't know how someone can even seriously suggest this. The camera processing pipeline for almost all actual cameras is rife with customization sliders for sharpness, noise reduction, saturation, etc. For what reason do you think those exist?
Literal TRILLIONS of photos are taken on iPhones every year. People are fine with them.
Most people are. Some prefer something different. Apple gave awards to Halide, a third party camera app with different processing. Your logic is absurd. It sounds like you're just mad that I don't like the iPhone camera. Like you think I'm not allowed to have my own opinion.
You watched a YouTube video about modern iPhone cameras and decided you needed to have a problem with it.
Now you're just making things up. It's explicitly spelled out in my OP that I bought an iPhone 14 Pro and then did not like how my photos were turning out so I returned it.
Your entire response is genuinely weird. It's as if you take offense to me having an opinion on the camera processing. I don't know why you care. The subject of the thread I created is the return policy. What do you think is going to happen, you're going to just convince me I actually like the sharpened 14 Pro photos?
